Why the N2XS(F)2Y is the ideal cable for your energy project

Why cable selection determines project success

Whether it’s a wind farm, industrial facility, or urban distribution network – when planning medium voltage, you’re deciding not just on cable lengths, but on system stability, reliability, and long-term operating costs. Cable selection has a greater impact than often assumed. While many components can be replaced, an installed medium-voltage cable quickly becomes a permanent part of the infrastructure – and therefore needs to be the right choice from the start. A cable like NA2XS(F)2Y performs precisely where others reach their limits. Below, we’ll show you why.

Typical challenges in medium-voltage cabling

Projects in the 10 to 30 kV range bring recurring demands – regardless of whether they involve new builds, modifications, or extensions. These include:

• High continuous current loads over many years
• Mechanical stress during installation (e.g., in tight cable routes)
• Interference from electromagnetic fields (e.g., in parallel routing)
• Compliance with IEC and VDE standards that must be met
• Different installation methods: buried, on tray, cloverleaf, etc.

The reality on construction sites shows: a cable that lacks flexibility, has large bending radii, or reaches its thermal limits too quickly not only delays implementation – it also endangers operational safety.

Why the NA2XS(F)2Y is ideal for modern energy infrastructure

The NA2XS(F)2Y meets these requirements with a well-thought-out, field-proven design. It is built for long-term operation under load and shows its strengths particularly in industrial and energy networks. Key features at a glance:

Technology you can rely on

When medium voltage becomes part of critical infrastructure, you need cables whose technical properties can be trusted – not only under ideal conditions, but especially when environmental factors, load, and system complexity increase. The NA2XS(F)2Y was developed precisely for such situations. Its design and choice of materials are aimed at maximum electrical safety, long service life, and seamless integration into modern energy projects.

Design: aluminum conductor, XLPE insulation, robust construction

The internal structure of the NA2XS(F)2Y follows a clear logic: conductivity, insulation, and protection in perfect balance. Detailed structure:

• Conductor: aluminum
• Inner semi-conductive layer: conductive plastics for field control
• Insulation: cross-linked polyethylene (XLPE) with excellent temperature resistance
• Outer semi-conductive layer: conductive plastic to limit the electric field
• Shield: lapping of bare copper wires (optionally with Cu tape) for effective electrical shielding
• Outer sheath: robust PE, mechanically durable and moisture-resistant

This combination ensures stable operation even under high thermal loads and in EMC-sensitive environments – provided installation is carried out correctly.

Designed for voltage classes up to 30 kV – standard-compliant and future-proof

The NA2XS(F)2Y is available in voltage classes up to 18/30 kV – for rated voltages up to 30 kV according to IEC 60502-2. This offers key advantages:

• International comparability in tenders
• Secure approval by grid operators or authorities
• Future-proof integration into existing or newly planned systems

For those who value planning reliability, technical clarity, and smooth documentation, this cable is the right choice.

Powerful, reliable, and durable

A good medium-voltage cable is not only defined by standards but by its ability to perform consistently under real-world conditions. The NA2XS(F)2Y was developed precisely for such demands – and offers technical advantages that truly matter in practice.

High current capacity for long-term operational stability

The cable is designed for continuously high current loads – without the risk of thermal issues, aging, or performance degradation. The combination of aluminum conductor and XLPE insulation ensures that the maximum continuous current-carrying capacity is maintained even under challenging conditions. Advantages:

• Reliable continuous operation even under full load
• The XLPE insulation shows a very low aging rate under normal operating conditions
• Less heat generation compared to inferior materials

Safe under short circuit and high thermal stress

The cable’s XLPE insulation also withstands short-term extreme conditions such as those that can occur during switching operations or fault currents.

• High short-circuit current resistance (even above 20 kA, depending on cross-section)
• With proper design and installation, the cable retains mechanical integrity even under high thermal stress
• Quick return to stable operating conditions

Strong EMC performance for sensitive environments

In networks with many parallel lines or sensitive control circuits, electromagnetic compatibility (EMC) is essential. The NA2XS(F)2Y is designed to minimize field interference and prevent voltage induction in adjacent lines. Your benefit:

• Fewer EMC issues during operation
• More stable measurement, control, and regulation systems
• Future-proof for complex automation environments

Practical application areas

The NA2XS(F)2Y is not designed for special cases – but for everyday use in projects where every meter of cable counts. Whether in industry, power distribution, or infrastructure – wherever performance, safety, and planning reliability are required, this medium-voltage cable shows its strengths.

Ideal for industrial plants, power distribution, and substations

In industrial environments, power flows are often permanently high, the load is continuous – and downtime is costly. The NA2XS(F)2Y is therefore a solid solution for:

• Production facilities with a constant load profile
• Transformer connections with high power ratings
• Distributions within larger industrial complexes
• Substations in municipal or regional network operations

Its high thermal resistance, combined with standard-compliant construction, ensures safety during operation – and reduces the risk of unplanned downtime.

Especially for complex network structures with EMC requirements

In energy-intensive projects with sensitive controls or parallel cable routing, EMC becomes a real issue. Here, the NA2XS(F)2Y scores with:

• The shield design in combination with proper grounding reduces interference on adjacent control and communication cables – especially in parallel installations
• Reduced susceptibility to interference in control, data, and communication lines
• Improved network quality through stable voltage transmission

Especially in wind farms, storage solutions, neighborhood grids, or in combination with decentralized feed-in, the cable offers the required interference resistance and operational reliability.

Easy integration into existing projects

The best technology is of little use if it’s difficult to implement in practice. Especially for medium-voltage cables, it’s crucial that they integrate smoothly into existing networks and new routing concepts – without additional planning effort, special solutions, or time loss on site. The NA2XS(F)2Y meets exactly this requirement. It is suitable for underground installation, open cable routes, and – with an adjusted bending radius – also for space-saving layouts such as cloverleaf configurations, offering high flexibility for a wide range of energy and industrial projects.

Underground, on tray, or cloverleaf – all possible

Whether in traditional underground installation, on an open cable tray, or in cloverleaf routing where space is limited – the NA2XS(F)2Y can be used wherever medium voltage needs to be laid safely, efficiently, and space-saving. This flexibility is particularly relevant for:

• Grid expansion for wind power plants
• Connection of transformer stations
• Construction of power routes in industrial areas
• Industrial plants with limited installation space

For planners and site managers, this means: the cable adapts to the project – not the other way around.

Plannable, compliant, and reliable

The NA2XS(F)2Y is certified according to IEC 60502-2 and meets all requirements for modern energy infrastructures. This provides key advantages:

• Clarity in tendering and planning
• Secure approval processes with network operators
• Smooth documentation and acceptance
• High operational reliability for decades

Anyone who buys a medium-voltage cable from KLZ receives not just a product – but a solution that is technically sound, compliant with standards, and ready to use. Especially in energy projects that need to be completed under time pressure or during ongoing operations, the NA2XS(F)2Y makes the decisive difference: no discussions, no rework, no compromises.
